Absolutely Position Element Within a Table Cell

Absolutely Position Element Within a Table Cell   Have you ever wanted to absolutely or relatively position a table cell? Well, I can't help you there. Table cell elements just won't take those position values. And thus, you also can't absolutely position elements within the context of those elements either. I can help you out with that issue. The answer is just to make a generic wrapper element inside the table cells (the exact same size of the table cell) and use that as the relative positioning context. Non-semantic? Yep, but we'll chuck that markup in with JavaScript so it's not a big deal. Kludgy fix? You know it. Does it work? Sure does. # Before < table > < tr > < td > < img src = " yay.jpg " alt = " " > </ td > </ tr > </ table > # After < table > < tr > < td > < div class = " innerWrapper " > <!-- appen...

A beginner’s guide to writing title tags and meta descriptions that get clicks

A beginner’s guide to writing title tags and meta descriptions that get clicks It’s true: title tags and meta descriptions won’t help your website magically rise to the top of the search engine results. Google confirmed it back in 2007 so let’s kill that myth right at the outset. However, these two elements can improve click through rates and entice people to click on your link rather than the link of one of your competitors. So why do site owners neglect title tags and meta descriptions, pushing them to the back burner? Title tags and descriptions tell search engines and users what your site is about. They describe the content on each page of your website and explain how it relates to a user’s search query. And, when used properly, they can act as a “hook” of your advertising in the search engine results. If you don’t know what title tags and meta descriptions are, why they’re important and how to write them to get more prospects to click on your links in search engine results, we’ll...

How To Use HTML Meta Tags

Image
Want top search engine rankings? Just add meta tags and your website will magically rise to the top, right? Wrong. Meta tags are one piece in a large algorithmic puzzle that major search engines look at when deciding which results are relevant to show users who have typed in a search query. While there is still some debate about which meta tags remain useful and important to search engines, meta tags definitely aren’t a magic solution to gaining rankings in Google, Bing, Yahoo, or elsewhere – so let’s kill that myth right at the outset. However, meta tags help tell search engines and users what your site is about, and when meta tags are implemented incorrectly, the negative impact can be substantial and heartbreaking. Let’s look at what meta tags are, what meta tags matter, and how to avoid mistakes when implementing meta tags on your website. What Are Meta Tags? HTML meta tags are officially page data tags that lie between the open and closing head tags in the HTML code of a document....

Meta tags that Google understands

-
Meta tags that Google understands Meta tags are a great way for webmasters to provide search engines with information about their sites. Meta tags can be used to provide information to all sorts of clients, and each system processes only the meta tags they understand and ignores the rest. Meta tags are added to the <head> section of your HTML page and generally look like this: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="Description" CONTENT="Author: A.N. Author, Illustrator: P. Picture, Category: Books, Price: £9.24, Length: 784 pages"> <meta name="google-site-verification" content="+nxGUDJ4QpAZ5l9Bsjdi102tLVC21AIh5d1Nl23908vVuFHs34="/> <title>Example Books - high-quality used books for children</title> <meta name="robots" content="noindex,nofollow"> Google understands the following meta tags (and related items): ...
